My experience is completely the opposite. I found the FTDI devices 
useless. They keep hiccuping or locking up completely. I've used the 
prolific devices in applications from intermittent bursts at 1200bps, to 
endless streaming at 460800bps. I also use them in applications where 
the adaptor is powering opto couplers, and the voltages end up way off. 
I've never had problems.
